IPC: H01L27/10
Filed: 1985-05-25
Abstract: PURPOSE:To interrupt the noise at the time of operation of a semiconductor memory device in a cell system of 1/2VCC and to obtain the DRAM having a large moise margin degree on the substrate by a method wherein the electrode layers are buried in the whole intercell isolation region in a reticulate form and these electrode layers are completely connected mutually in a low-impedance. CONSTITUTION:An SiO2 film 11 and an Si3N4 film 12 are superposed on an Si substrate 1, a groove 14 is formed by an RIE method and after an SiO2 film is formed on the internal surface of the groove, an Si3N4 film 15 is superposed by a decomposition CVD method. The Si3N4 film 15 is left on the wall of the groove by an RIE method and an isolated oxide film 3 is formed at the bottom of the groove. After the film 15 on the upper part of the wall of the groove is etched away, a P-doped polycrystalline Si layer 10 is superposed and after an etching is performed on the whole surface by an RIE method and the layer 10 is removed up to the same surface as that of the substrate 1, the films 13-11 are etched away in order. A cell electrode 5 is formed on a new gate oxide film 4, an Al wiring is formed in the buried electrode 10 and the potential is fixed at the earth level. A large capacity is formed between the cell electrode 5 and the erathed electrode 10 and the noise to be impressed on the electrode 5 is absorbed in the capacity. According to this constitution, the noise is effectively interrupted even at the time of operation of the memory device in a cell system of 1/2VCC and the DRAM having a large noise margin can be obtained on the substrate without using an epitaxial layer because the conductor pattern having a stable potential is buried in the field isolation region.

Abstract: PURPOSE: To suppress hardening of the toe of weld of beads and prevent the occurrence of corrosion cracking in weld zone by specifying the carbon equivalent of base metals, preheating temperature and welding heat input at the time of laminating the final pass with the site joint of a spherical storage tank.  
     CONSTITUTION: In the case of laminating the final pass under the conditions in which welding heat input is ≤24Kj/cm with the site joints of a spherical storage tank, the upper limit of the carbon equivalent of base metals is kept at 0.40%. The threshold cooling time (11sec) when the maximum hardness of the base metals becomes ≤300Hv at the upper limit of this carbon equivalent is obtained, and in order to assure the cooling time 11sec at the minimum heat input quantity (for example, 12Kj/cm), the continuous preheating of 150°C is performed at the preceding bead application of the final pass. While the interpass temperature is being secured at ≥200°C by using the heating by this preceding bead heat input, the final beads are applied. Thereby, the cooling time of the weld bond zone of 800W500°C may be sured for ≥11sec and the joint hardness may be kept at ≤300Hv.
